truncate: use O_WRONLY|O_NONBLOCK
...
This matches coreutils behavior. We don't read the fd, and truncation
does not need blocking.

Fix this by simply always setting the mode, as it doesn't hurt even
when O_CREAT is not specified.

truncate: do not die when a file doesn't exist and no-create flag is on
...
Additionally, open(2) failures do not make the program die immediately.
This makes the behavior of the program match coreutils more closely.
